I have never seen or heard of that before. I've been through several sets of 103s on my set-up and never had a separation issue. Heck, I could even re-use these in other cars if I wanted to. Some attention from a wirebrush, and a different gap and good to go.

Correct, this is the Duratec Performance '08-'11 section for MkII owners.

Try the MkIII sections, your engine type is Duratec TiVCT.

Welcome to FF, you should find a lot of info. once you get into the MkIII sections & general areas that fit all models.

Stock plugs are Motorcraft SP-535

well I changed my spark plugs today in my new to me 06' Focus. I used Autolite 104 coppers. I did not know the mileage of the plugs, but the previous owner had put Bosch platinum's in her! they didnt look too bad, electrode was worn. I guess on the bright side they were not factory at 200XXX KM's ;) I was greeted with better start up, better accel espcially in 1st gear and a smoother idle. Thanks everyone!

When you change your plugs, use either anti-seize or go old skool and use a dab of oil on the threads of the plugs to they don't corrode in the head.

I'm really late to this, but Music if you're looking for an 08-11 shop manual, I uploaded mine and was giving it out to members.
